Does anyone have any experience with the Crossfire Pressure Equalization Systems? I'm trying to find out what kind of valve stems I will need to make the connections and I haven't found the information on their web site?

I'm getting new tires (296/75R22.5) installed on our motorhome on Monday and my Crossfires were supposed to be in yesterday but now won't be in till Tuesday so I'm at a disadvantage on knowing what kind of valve stems I need to get installed when the tires are installed. Currently I have a mix of short straight stems and medium length 45* stems. To add to the complexity, I'm installing Centramatic balancers at the same time so I will only have 2 hand holes to work through after the new tires are on.

Thanks in advance for any information you can provide.
